Hi Guys, Does the new rope need to go on under tension like the steel wire. I have just bought 30m of the blue rope.

Thanks

It does Christian.

One of the issues with the rope is that it pulls thru , i.e. top layer will pull thru and can jam under a lower layer so putting it on needs to be done carefully and tension helps reduce this.

I only put 20 of 30m on my winch and made an extension strap with the other 10m to help reduce this effect.

Thanks for that Robin, I thought it would pull through the other layers like the steel wire does if that is not put on under load.

G`day Christian,
I have just put 125 ft of Amsteel Blue rope on my winch and the instructions said to put the first layer on straight and then lay the rest on at about 30 degrees in a hatch pattern,each layer at the opposite angle to the previous, this prevents any "Burying" of the rope remaining on the drum when being used under tension.
It just needs to be at some tension ,not a lot.

Some fishing reels have this feature to enable longer casts.

Regards,

Scrubby.

Steel rope has to be tensioned for sure but that is done by winding out the wire to the last three strands on the drum then loading it up by hauling the car along with s good degree of tension on it. The purpose is to remove most of the memory that occurs in the manufacturing process of wire rope. Quite amazing to watch the wire literally unwind in front of your eyes. But this is a marginal but noticeable change

For blue rope (I am assuming Dyneema) and all synthetic ropes there is no memory in the same way as wire rope so the process described above is not required.

Comments regarding birds nests are interesting but this will almost always occur when winching in under load so is normal and occurs regardless of synthetic or wire ropes. So when this happens you need to wind it out then rewind on to the drum under very light tension. We have been using Dyneema for over ten years now and never had an issue with it. But we service our winches every six months and the rope gets washed probably every three months or more often if it is dirty

Regards

Dunno much about synthetic rope but have had a lot to do with steel rope ( on mine winders) To get a rope to run properly the fleet angle must be correct, which I do not think would be possible when winching a vehicle, but it must be tight on the drum.. The lay of the rope is very important when putting on the first layer. Most ropes are right hand lay. To fit the rope to the drum a simple rule applies. RHR hold the right had out, palm down, index finger pointing in the direction of the pull and anchor the rope to the left hand side of the drum with the rope passing over the top of the drum.

I must add that the more times that the rope does not lay properly the more the rope will wear. Crossed rope should be relayed asap.
